Abstract

In this paper is investigated an emerging technology called “power electronics” with an evaluation of its potential for air conditioning and heat pump applications in Florida. The study also addresses the power savings to be expected for the customer and for the utility in its management of load. Furthermore, data and a computer flow chart are provided so that the information herein may be transferred and used by engineers in other geographic regions for their specific utility systems. Four heat pump models are developed and their performance analyzed and compared with each other specifically in regard to Florida climates. These models are a conventional single-speed, two-speed, variable-speed, and Oak Ridge National Lab variable-speed systems. Some of the results indicate that generally the major advantage - “greater efficiency” - of power electronic based variable-speed variable-capacity heat pumps is due to the higher coefficients of performance and energy efficiency ratios resulting from oversized heat exchangers, and the decrease of cycling losses that result from on/off operation which must occur when capacity exceeds load. © 1992 IEEE
